Description
Technical field
The present invention relates to the preparation method of a kind of modified cocos nucifera oil, be specifically related to the preparation of the dedicated modified cocos nucifera oil of a kind of suckling piglet
Method, belongs to feedstuff cocos nucifera oil processing technique field.
Background technology
The piglet stage is the stage that the whole growth cycle of pig is the most key, and late growing stage is played extremely by its nutriture
Crucial influence, therefore the feeding and management level in piglet stage is also closely related with pig farm benefit.It is known that piglet goes out
After life, digestive enzyme lacks, gastrointestinal tract pH value is higher, gastrointestinal microflora progressively field planting, immune performance are poor, thermoregulation
Ability is more weak, and it is higher to the demand of dietary nutritional standard that the physiological characteristics of these uniquenesses decides the piglet stage.Especially, due to
Newborn piglet basal metabolism is high, thus the highest to the demand of energy, and energy under-supply be to cause that newborn piglet is dead, wash in a pan
The key factor eliminated, the especially body weight small and weak piglet less than 0.8 kg.It addition, generally exist in Sheng Chaning from birth after until
The fatty diarrhea of the suckling pig of wean, this is owing to first Ruzhong lactose is low, lacks Short-Chain Fatty Acids, and piglets is to breast milk energy
Again can not be to caused by the digestion of long-chain fatty acid in breast milk while amount demand.
Cocos nucifera oil is unique natural oil containing a large amount of Short-Chain Fatty Acids, is easily absorbed by young stock, is suitable for piglets material
With ablactational baby pig feedstuff.Research shows, adds the Oleum Cocois of equal proportion and the mixing of soybean oil in early days in ablactational baby pig daily ration
Oil, piglet growth performance is substantially better than the compositions that other are adipose-derived；MCT Oil (MCT) is high due to it
, can easily absorb, be widely used in poultry, cattle breeding, external numerous results of study show, add in pig starter feed
MCT, can be effectively improved piglet survival rate, and beneficially pig weight increases.Further, since medium-chain fatty acid have special
Chemical constitution is known, it can quickly enter the lipid layer of bacterial cell membrane, in causing by destroying bacterial cell membrane structure
Tolerant loss, transport mechanism are destroyed and play the effect of suppression antibacterial, are important feedstuff antibacterial, apply energy in feedstuff
Reduce the use even avoiding antibiotic.
Owing to cocos nucifera oil and the MCT application in feedstuff has the function of uniqueness, utilize its exploitation feeding product of high-quality
Front border, market is the most optimistic.CN201210164946.2 discloses a kind of diet fat source group that can improve intestine of young pigs health
Close, Oleum Cocois in Piglet Diets: fish oil: Adeps Sus domestica is 1: 1: 1 by weight；CN200610045413.7 discloses a kind of feedstuff and uses
Mixed emulsifying oil and production method thereof, described mixed emulsifying oil includes Oleum Cocois.But above patent provide only with Cortex cocois radicis
Oil is the feed combinations of raw material, the technology of preparing of the functional grease not provided, and owing to the source of raw material is different, Cortex cocois radicis
The Short-Chain Fatty Acids of oil and the composition of triglyceride there may exist diversity, are unfavorable for the control on producing.Therefore, there is skill
Cocos nucifera oil is modified by art, is generally hydrolyzed to obtain fatty acid for raw material with Cortex cocois radicis core, occurs esterification anti-with glycerol the most again
MCT should be prepared, or with other Material synthesis MCT.CN201310010797.9 discloses a kind of fixed lipase catalyzed legal system
The method of standby glycerol monolaurate, it is to be mixed with glycerol by Oleum Cocois, carries out ester using immobilized-lipase as catalyst
Exchange reaction, then obtains glycerol monolaurate finished product by steps such as centrifugal, molecular distillations；Lu Tianhua joint-stock company technology
Center is then with octanoic acid, capric acid, and glycerol is raw material, catalyzes and synthesizes and prepares decanoyl/octanoyl glycerides product.But these technology not only walk
The most numerous and diverse, time consumption and energy consumption, does not particularly require the structure composition of triglyceride, thus causes preparation cost higher, feeding
The situations such as effect of oils and fats not maximization, this is also current technology common problem simultaneously.
Summary of the invention
It is an object of the invention to provide the preparation method of the dedicated modified cocos nucifera oil of a kind of suckling piglet, according to energy needed for young piglets
The construction features matter structure of amount, body fat metabolic pathway and MCT Oil MCT and cocos nucifera oil makes preparation Sn-
1,3 is the modified cocos nucifera oil structure ester of middle low carbon chain fatty acid, and the method not only technique is simple, preparation cost is relatively low, and makes to produce
Product effect maximizes, and the modified cocos nucifera oil product prepared, and can meet the market demand, it is thus achieved that good economy and society's effect
Benefit.
The preparation method of the dedicated modified cocos nucifera oil of a kind of suckling piglet, comprises the following steps:
(1) by oils and fats 20 ~ 60 parts, emulsifying agent 1 ~ 10 part, the mixing of 20 ~ 80 parts of water, being heated to 40 ~ 50 DEG C, 500 ~ 1000r/min stirs
